    So over the past few days I've been reading threads from here and 9thgencivic about adding in an aftermarket sub for my 13 Si with premium audio and nav.

    I think I have everything down but I'm still having trouble understanding how to do it. I would like to keep the factory amp running everything but the sub. I'm on a budget of about $250 for an amp so I can't afford anything fancy that has balanced inputs like a JL(even though I'm running a JL W7 12 that I got used for 100 bucks), and one of the more informative threads on 9thgen relies on a balanced line driver that Rockford Fosgate doesn't make anymore. I'm not looking for an uber high-quality listening experience, I just want more bass in my car.

    From what I've read, I should be able to go to the 24 pin connector on the factory amp and cut and splice in a speaker wire to RCA adapter to the SUB+ and SUB- wires and then run RCA cables directly back to the trunk. I would also tap into the 24 pin connector for the amp remote wire.

    Am I missing anything? If so can someone explain to me what exactly what I need to do? Thanks

    So After reading that , I should be able to use this https://www.crutchfield.com/S-u78bm1dW97B/p_136CLRLC/JL-Audio-CL-RLC.html for the balanced inputs? Just chop the pre-amp and replace with RCA then wire that in and send that back to the amp. Leaving the control knob from the amp to take care of adjusting bass.
